In this letter, a novel robust scheme with antenna array and global positioning system/strapdown inertial navigation system (GPS/SINS) is proposed for improving the anti-jamming capability of navigation receiver. The key idea is that the apriori knowledge for beamforming is supplied by satellite almanac and tightly coupled GPS/SINS. Then a multiple constrained minimum variance-spatial temporal adaptive...
The principle of airborne ocean wind-field detecting system based on GPS scatter signal is proposed. The architecture of Doppler Delay Mapping Receiver (DDMR) was introduced in this paper. Six key techniques were discussed such as improving the Signal Noise Ratio of reflected signal, dual radio frequency front-end, calculating the specular point for Doppler and code delay, implement for multi-channel...
